Andreas Jaeger 6b083d46e4 * nis/nss_nisplus/nisplus-ethers.c (struct etherent): Removed.
* inet/ether_hton.c: Likewise 
* inet/ether_ntoh.c: Likewise.
	* nis/nss_nis/nis-ethers.c (_nss_nis_getntohost_r): Fix
	declaration to match prototype.

	* include/netinet/ether.h (struct etherent): Declare here so that
	all implementations use the same struct.

	* nis/nss_nis/nis-ethers.c: Include netinet/ether.h to get
	prototypes.
	(struct ether): Removed.
	Use struct etherent instead of ether everywhere.

	* include/rpc/auth.h (DECLARE_NSS_PROTOTYPES): New.

	* include/rpc/auth_des.h (DECLARE_NSS_PROTOTYPES): New.

	* sunrpc/publickey.c: Include auth_des.h for prototypes.
